This paper presents an experimental investigation of heat transfer processes and the temperature regime in a turbulizer-equipped solar air collector. The experiments were conducted on May 23-24, 2025, during which the hourly variations of ambient air temperature, solar radiation intensity, and the temperatures of the transparent cover, absorber, and working air of the collector were analyzed. The ambient air temperature varied within the range of 29.9-39.2℃, while the solar radiation intensity ranged from 237.4 to 957.0 . The results revealed that under solar radiation intensities of 800-1000 , it is possible to obtain hot air with a maximum temperature of 74℃ at the collector outlet. The findings demonstrate that the use of turbulizers enhances the intensity of heat transfer and significantly improves the thermal efficiency of the system.
